' EEBOSSING AND PRINTING MACHINE.

To all as]: am it )1: ay concern:

Be it known that we, Tnonas J. Enwanns and Warm P. Oscoon, citizens of the United States, at Melrcse, in the coun ly of Middlesex, State of Massachusetts, and at Maiden, county of Middlesex, State of Masaehusctls, respectively, have invented a certain new and useful Improvement in Embossing and PrintiiLilg Machines, of which the following is a spee' cation, reference being had therein to the accompanying drawfie invention has for its object to provide means to feed prepared gold, silv er, aluminum, and other transfer material, meluding color, in an embossing or printing machine into position between the worksupport or backing and the or printing-die or surface, so that the required imprint in gold or the desired other material or color may be produced upon the work.

The invention consists mnfially in the combination, in an embosmg' or rinting machine, with a work-support or and a printing-die or surface, of means for feeding the prepared gold, etc., between the work-support or backing and die or surface so as to mtervene between the work and said die or surface.

An embodiment of the invention in the preferred form is shown in the drawings, in which latter;-

an expanding spiral spring 14, Fig. 2, to give yielding and prolonged pressure of the backing a mst the work when the eccentric 8 moves e plunger forward. A suitable band-pulley 10 is mounted upon the said shaft 9. In practice, clutch-devices and a controlling treadle therefor will be employed for connecting the said pulley to the said shaft at will, to cause a rotation of shaft- 9 and an embossing or printing action to take place, and the machine to then come to rest with the backing 2 separated from the die, in readiness for a second operation. A yoke-shaped forward extension 11 of the machine-frame supports an electric-heater 12, the body of which constitutes a support for the em die 13. The said electricheater or die-ho] er, and the die, are located within the recess of the yoke, and the die faces rearwardly. The acting surface of the die is vertical, and so is that of the backing :2, to provide for the insertion of the work to be embosed or imprinted, for instance the top portion of the upper of a shoe, in a vertical position from below, the front lower portion of the machine-frame 1 bein constructed to ive clearance to the wet and avoid interference therewith, thus permitting the work to be inserted as stated and the lower part thereof to occupy a position below the die 13 and backing 2.

The invention provides means for feeding prepared gold or other transfer material, from a source of supply into a position between the backing 2 and the die 13, so that the said material shall intervene between tire workf aphid lthe die, anlddso that 111v ge cosingo e ackm' gan 'etoget er e work and the said material shall be compressed together between the backing and the die. The prepared gold, for instance. in the form in which we employ it is in the shape of a slip of sheet material. as paper. having a superficial coating or layer of the gold. A supply of slips is placed upon or 100 a suitable holder therefor and the slips are successively fed into position adjacent the die. We preferably employ a carrier, and means for feeding the slips in succession from the supply-holder to said carrier, the latter acting to place each slip in turn in the said position. The feeding means, in the prepared embodiment thereof. comprises, essentially, a separator, which may be in the form of a picker, preferably 110 pneumatic, and a transferrer which transfers the separated slip to the carrier.

In Figs. 2 and 4 a supply of prepared slips o is shown supported by a shelf 14 occupying an elevated position in the machine, and carried by a supporting arm 14. Opposite neumatic pickers are shown at 15. if), they Being elastically mounted through being carried by opposite arms of a bent leaf-spring 16 extended transversely of the machine, the middle of the said spring being attached to the forwardly-pmiecting arm of a earner 17 which is pivoted at- 18 upon a support 19. Pipa :20, 20, connect the pickers with a chambered portion of carrier 17. the chamber having an outlet which is in communication by means of a flexible tube 21 with the cylinder 22 of a suction pump, the piston rod 23 of which is connected to the pin of a crank-arm 24 fast upon a shaft 25 driven by gearing 26, 27, from the main shaft 9. To cause the pickers to touch the surface of the top slip of the pile resting on the 14, and then lift the same to separate it from the next succeeding slip, the earner 1| is given a rocking movement. This movement is occasioned in the present mstance through the engagement of the stem of a screw '28 within the slot 9.9 extending lengthwise of one member of a two-part extensible connecting link 30, 31, its other member 31 connected by a pivot 32 to the actuating slide 33 of the transferrer. The member 31 is slotted longitudinally at 31, 31", to receive the stems of the screws 30, 30", which secure the two members adjustably together. The said slide 33 is actuated in one namely, to lift the pickers from the pile of slips, the contactofa cam3-ttthatiscamedbyshaft :25 with a roll 35 mounted upon the said slide 33, the slide being moved in the opposite direction. to allow the pickers to descend upon the top of the pile, by the tension of a contracting spiral spring 36, Figs. 2 and 3, which engages with one arm, 37, of the transfer-rat, to which arm the forward end of the slide 33 is pivoted by a screw 38.

In order that the movements of the pickercarrier and pickers toward the pile a may vary to suit the height of the top of the said pile, the longitudinal slot 29 is provided in the connectinglink 30, 31. In the rearward movement of slide 33 and link 30, 31, one end-wall of the slot 29 encounters the screw 28 and turns the pcker-carrier to raise the picker-s and the slip'engagcd thereby, the tops 3T", 3?", of. the transferrer arms passing in between the said slip and the remainder of the pile a. The slip is detached from the pickers during the ascent of the latter by meansof an overhanging piece 38 projecting'forward from a bracketof support 19 over the pile a. This detaching piece 38' is located atsuchheight above the shelf'that as the picker-carrier and pickers rise, taking a slip with them, the slip is lifted high enough to permit the passage of the transferrer 37 between it and the pile, before the encounter of the slip with the detaching piece disengages it from the pickers. When the slide 33 is moved forward, producing a forward movement of the transferrer which carries forward the separated slip, the pickercarrier is permitted or caused to rock so as to carry the pickers into contact with the top slip of pile a. This rocking may be due to the. gravity of the forward portion of the picker-carrier, aided by a spring if desired, or a spring may be chiefly depended upon. In Figs. 1 to 4 gravity is relied upon. but in Fig. 6 an expanding spiral spring 29 is shown confined between a projection 29" from member 30 and the head of screw 28- Said spring is threaded upon a pin 29 se cured in said projection and working in a hole through said screw head. The spring acts expanaively to hold the screw :28 in contact with the forward end of slot 29. When, however, the pickers encounter the top of the pile a in their descent, the spring 29* yields to the resistance which oppm further descent of the pickers.

The transfer-rel comprises opposite arms 3T, 37, attached to and rising from a small supporting shaft 39. The upper ends of these arms are in the form of curvedseg ments 3?", 37, which are notched upon their tops,- as shown best in Fig. 2, to receive the end rtions of the upraised slip. The note ed portions of the transferrer pass in beneath the ends of the upraised slip before the slip is detached from the pickers, and the detached slip rests within the notches. The

errer then is swung forward to deliver the slip to the carrier.

The carrier shown at 40 comprises opposite side-arms that are mounted pivotally upon a small cross-shaft 40', Fig. 2. Each of such side-arms is provided with a slipholder or clip 41 constituted by a strip of spring-metal bent uponitself so that the end-portions of a slip carried forward by thetransferrer may enter between the two portions ofthe slipholder.- The carrier is actuated to move forward into its position in the drawings by means of avcam *2 on shaft 25 engaging a roll 43 carried by a slide 44. which latter is pivoted at its front end by screw l5 to one arm of the carrier. 1 contracting spiral spring 46 which is engaged the said slide acts to move the carrier rearward to receive a slip. At 59, 50. are side-guides supported from the support 19, and having slotted gnideways along which tbeends of the slip pass while the slip is being advanced by the error. These guides prevent the slip from becoming separated fro'm-the transferrer, and conductits end-portions into the clips of the carrier.

xllhe supp rt 1 for he shel il tis attache to thei plunger 7., and the tranisierreiwand carrier, are ,both pivoted; 9 the. base-portion Taenable the shelf. tobeiadiusted vertioally t o suit the, size of; the pile a, the arm 4:? of such she fha's itslo er and ea ward extremity-entered into a vertical, slot 60 of support 19 A rearwardly projecting. stud carr ed; by the. said. arm oun-e a e by a n 6 s. a-s an -p an & i l '16 i g: wh l 6 ic is' ted r ra ally I upon thesupport-19. This wheel maybe rotated. .by. hand conveniently. from time to time whenever the' top of, the-piled requires to be raisedor lowered tobringit into proper position with r'elationto. the pickers. 1. The p c er m y be mr ii f; sh rtwations ofrubber-fuhing set-seas to diverge slightly fromeaoh. other, as ,in,. F-ig i, but preferably we employ; theconstruction shown in Figs. 5 .and. 6. .In thelatter constructionthepickers 15%, 15%,},may heroin; posed entirely of metal. H They are separat'ely'forinjedf and; re mounted pivotally upon the piclrer carr1er=17"by means of a screw 15', located between thetwo. pickers and engaging with ears of'thelatt-er projecting inwardly from. thempper; portions of the pickers. The opposite ends of a leafprin 15- attached: to the;pickennarrierf11% bears upon the tops of the pickers andheidsrr them in the depressed position relative to each other and to the picker-carrier that is represented in Figs. 5 and 6. In the case of both constructions, when the pickers in their descent take bearing upon the top slip a they spread apart more or less, swinging outward away from each other and slipping or sliding upon the top surface of the top slip 0;. As the picker-carrier is swung reversely and the pickers rise, they spring toward each other again, and this produces a buckling upward or downward of the top slip between the pickers, separating such slip from the next succeeding slip and affording opportunity for the entrance of air between the two slips to facilitate the separate lifting of the top slip.

By the curved guideways 50, 50, the ends of the slip that is being transferred are conducted to the carrier so that the entrance of such ends into the openings of the carrier clips is assured, and failure to enter, as on account of the slip being bent or its ends being dropped, is obviated. In the rearward movement of the carrier the upturned extremity of a clip strikes upon the forward end of the corresponding guide 50. This opens the clips. In the subsequent forward movement of the carrier, as the clips leave hold-blllesaidends firmly.

lVLountin-g the carrier and. other. parts upon, the plunger 7 enables the carrierin its descent with a slip to carry the-latter down sulfioientl'yto. the rear-of the die to clea the die. The carrier then moves forward in unison with the ram or backing, its

clips being'thereby advanced clearof the workso asytocarrv the slip to the die. The

transfer-re and't-he shelf 14: are mounted upon the plunger in order that they may accompany-the carrier. in its movements, which renders it easier to. maintain proper working relationship. .ofthe transferrer with .;respect to the carrier, and of the transferrerz-;and shelf with respect to-ea'ch othen: fT-headvanceof the carrier relative to the die carries the slip against the die and bends theslip somewhat, drawing the ends of the slip out'of' the clips of the carrier as the impression is taken. This enables-the carrier to rise and move rear wa-rd toward thetransferrerto receive an- 0131191781113, this movement. being permitted by reason of the detachment of the slip Wliihhhas justdoeen fed from the carrier.

-The machine: stands at-z-rest with the car'- riereelevated a-short distance above the die. andcontaining a slipiain readiness for the next- .i-mpression or. printing.- operation. iVhen-theetreadle is pressed upon to call the machine into action for an embossing-1 operation), the :carrierxmoves down the short .adlsta'ii'ce required to place the slip in front of the die, and whenthe carrier has become detached from the slip it moves back to the transferrer, receives a fresh slip therefrom, and resumes its position just above the die. This position holds the slip sufliciently removed from the heated die to protect the slip from the heat of the die While the machine is standing still. The prepared slip of gold is more or less saturated with paraflin, which would melt if the slip were allowed to keep a position close to the die while the machine is not' in action.

The special. features of the pickers herein shown and described form the subject of a divisional application.
